' MACHINEFOR JBARBlNG FENCE-WIRE.

SPECIFICATION forming part of Letters Patent No. 280,629, dated July 3, 1883.

Application filed May 4,1883. (Model.)

To a/ZZ whom it may concern.-

Be it known that I, AXEL JonGENsEN, of

Des Moines, in the county of Polk and State of Iowa, have invented certain new and useful Improvements in Machines for Barbing Fence-Wire; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enableothers skilled in the art to which it appertains to l machine'with part ofthe frame broken away.

Similar letters of reference indicate corresponding parts in all the figures. Y

My invention has relation to machines fo barbing fence-wire; and it consists in the improved construction and combination of parts of the same, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicates the main shaft of the machine, which is journaled in suitable bearings and rotated by any suitable means. Upon thisv shaft is fastened an eccentric disk, B, which revolves between the bifurcated ends of an arm, C, at the upper, end of which lis formed a circular disk, D, through the center of whichl disk the strand-twisting shaft E passes. Disk D is fastened upon the face of the bearing F, in which the twisting-shaft rotates by means of two headed bolts, G, passing through curved slots H in the disk into the face of the bearing, the curved slots allowing the arm and head to be rocked by the drive-shaft and eccentric disk.

Two grooves, I, extend from diametricallyopposite points upon thesurface of shaft Ein opposite parallel directions toward the interior of the shaft, and the strand-wires .I are fed from suitable reels through these grooves out to the barbing mechanism, being twisted -by the revolution of shaft E. This shaft is revolved by means of a segmental rack, K, which is fastened upon the upper end of an arm, L,

pivoted at its lower end upon the frame-work of the machine and rocked by means of the wrist-pin M of a crank,'N, sliding in a longil! tudinal slot, O, in the arm'. As the driveshaft Arevolves, upon which crank N is fastened, the wrist-pin, traveling up and down in the slot O, will rock arm L, and the rack K will revolve a pinion, P, turning upon thetwistingshaft alternately in opposite directions, and a disk, Q, fastened'to and concentric with the pinion. A spring-pawl, R, is pivoted upon the other side of disk Q and engages a ratchet-tooth, S, upon shaft' E, so that the shaft is revolved with the pinion when the rack is rocked to one side, while the pawl allows the -pinion to be revolved in the opposite direction when the rack is rocked to the other side. Two vertically-slotted lugs or barb-holders, T, are fastened to the front of disk D, diametrically opposite each other, and serve to hold the barbblank Y, and, as the disk is rocked or oscillated',

to give it a preliminary bend, the barb being fed between the strand-wires and held by the slotted curved ends of the barb-holders. From the upper `edge of disk D an arm,'U, projects laterally, through the outer forwardly-bent end of which passes a set-screw, V, which bears with its lower end against the movable cutter IV, which is fastened upon arm U, and which operates, in conjunction with the rigid cutter X,to clip the barb-wire which passes between the-cutters into blanks of the proper length. It will thus be seen that as the strand-wires pass out at the ends of grooves I the barbblanks are inserted between the two strands, cut off/as arm C rocks to one side, and slightly bentl as the arm rocks to the other side, Whereupon the twisting-shaft is revolved, bending the barb around the wires and twisting the wires, which thereupon are wound upon a reel suitably arranged in front of the twisting mechanism.

. Having thus described my invention, I claim and desire to secure by Letters Patent of the United Statesl. rlhe combination of the shaft A, having Cutter X, and strand-twisting shaft E, hzwmel; K und slot O, und ernnk M N, ull eoning` grooves I and means for revolving;` it, as strneted to operate as and for the purpose and for the purpose shown and set forth. shown and set forth.

2. As an improvement in barbing-lnaehines In testimony that l, claim the loregoing :is 5 for fence-wires, the combination and zu'mngemy own I have hereunto ai'ixed my signature 15 ment of shaft A, eccentric disk B, bifurezited in presence of two witnesses.
